Chart Pattana Party (2007)

The Chart Pattana Party (Thai: พรรคชาติพัฒนา, English: National Development Party) is a Thai political party. The chairman of the party is Wannarat Channukul. His brother-in-law, the party's "chief advisor" Suwat Liptapanlop is however considered its de facto leader.

It was founded under the name of Ruam Jai Thai Chart Pattana ("Thais United National Development Party") as a merger of Thais United and the former National Development Party in September 2007. In the Thai general election, 2007, the party received enough votes to gain eight out of 480 seats in the House of Representatives of Thailand. After 2008, the party was a member of the six-party coalition government led by the Democrat Party's leader, Prime Minister Abhisit Vejjajiva. The party's leader Wannarat Channukul was Minister of Energy in Abhisit's cabinet. The party name was shortened to Ruam Chart Pattana.

In 2011, the Ruam Chart Pattana Party merged with the Puea Pandin Party and changed its name to Chart Pattana Puea Pandin. In the election on 3 July 2011, the party won 7 of the 500 seats in the House of Representatives, five constituency-based and two on the party list. Four of its constituencies are in Nakhon Ratchasima, the party's stronghold and home province of its leaders. After the elections and Pheu Thai Party's victory, the party agreed with Pheu Thai and three other minor parties to form a coalition government under the leadership of Yingluck Shinawatra. Later in 2011, the party name was again simplified to its current version.
